Application 'May 18,

11 Claims.

This invention relates generally to smoking devices, and particularly has to do with a pipe.

One object of the invention is to design and construct a pipe having a removable bowl, and an air chamber around the bowl for the purpose of supplying an additional volume of oxygen, so as to more fully insure proper combustion of the tobacco, as well as eliminate undue heating of the pipe in general.

Another object of the invention is to provide an offset on the body of the pipe, which is of such a character that the ends thereof will respectively detachably support or carry a pipe stem, and a receptacle for foreign deposits.

Another object is to provide a system consisting of one or more passagewaysthat communicate with the air chamber surrounding the bowl the passageway in the pipe stem, and which may be so arranged that there is practically no opportunity for the smoker to experience what is called tongue bite; and this arrangement, including the provision of an auxiliary passageway, arranged in the system of passageways, also serves to entrap any foreign matter, such as tobacco ashes, nicotine, and saliva, whereby to prevent the same from entering the mouth of the smoker through the pipe stem. The passageways and air chamber are preferably so arranged that the receptacle serves as a sump for the nicotine and saliva, while the small particles ,of tobacco and ashes that happen to drop through the holes in the bottom of the bowl will be retained in the air chamber surrounding the bowl.

It is also contemplated to so design and construct the various passageways that the smoke is caused to travel along a tortuous path, in order that the carbonaceous impurities in the smoke will not pass into the mouth of the smoker, and this of course insures a mild, cool refreshing smoke.

A further object of the invention is to arrange a relatively small chamber in the system of passageways, preferably at a point adjacent the lower end of the pipe stem, so that if it is found desirable, a suitable material may be located in the chamber so as to filter the smoke before it enters the mouth of the smoker.

A still further object of the invention is to so design and construct the various passageways and chambers, including the various parts comprising the pipe, that all may be easily and quickly cleaned.

Other objects and advantages will appear after 1936, Serial No. 80,227

considering the following description in connection with the drawing annexed hereto.

Referring to the drawing wherein the details of the preferred principles of design and construction of the smoking pipe are clearly shown, and the various parts are designated by numerals:

Figure 1 shows a vertical section of the preferred embodiment of my invention; Figur-e 2 is a vertical section of another embodiment of the invention; and

Figure 3 is a vertical fragmentary section of a third embodiment similar to Figure 2, showing another way whereby to provide an air chamber surrounding the bowl of the pipe.

Referring first and more particularly to the preferred embodiment of the invention shown in Figure 1, numeral 1 generally designates the pipe body which is formed to include a cup 2, which supports a bowl -3, and an integral offset portion 4, which is preferably so constructed that the upper and lower extremities or extensions 5 and 6 thereof will respectively removably sup- .port a suitable stem 1, and a receptacle 8 providing a sump for foreign deposits.

The body of the pipe may be made from any suitable material, such as a phenolic condensate, and is preferably formed to provide an air chamber 9 in the cup surrounding the bowl 3. As clearly shown, the upper extremities of the cup 2 and bowl 3, are respectively provided with inwardly and outwardly extending annular portions l0 and l l, which are so constructed that the bowl 3 is adapted to form a friction fit with the cup. The bowl, which is preferably made from a suitable refractory material, may be otherwise detachably attached to the cup 2. Suitable apertures l2 are provided in the bottom of the bowl 3. The air chamber 9 serves to provide an additional volume of oxygen under the burning tobacco so as to support the proper combustion and uniform burning thereof when the pipe is laid aside, and otherwise, said air chamber also serves to insulate the bowl from the cup 2, and this prevents the pipe proper from becoming heated to any great extent.

As to the construction of the pipe stem 1-, and the manner in which the same is carried by the extension 5 on the ofiset 4 of the pipe body, it will be noted that the inner tapered end l3 of the pipe stem is adapted to cooperate with a tapered hole l4, providing a seat therefor; and in order to prevent splitting of the extension, a ferrule I5 "is preferably arranged therearound. Ii 5 to be understood that the pipe stem may be made of any suitable material, and may be made straight if so desired, but as here shown, the stem is curved, and has a passageway l6 extending therethrough.

It is to be noted that the tapered hole M in the extension 5 is of a certain depth, and that the inner end 3 of the pipe stem extends inwardly a predetermined distance, in order to preferably provide a relatively small chamber or pocket H, in which, if so desired, may be placed a suitable fibrous or cellular material 25, impervious to moisture, that will act as an agent to filter the smoke as it is drawn out through the stem by the smoker.

If found desirable, the filtering material may be impregnated with some suitable chemical so that the smoke will be purified or be given a slightly different pleasing taste; Obviously, any

mixture of saliva and nicotine in the" passageway IE will drain into the pocket H.

In order to establish communicationbetween the air chamber 9 surrounding the bowl 3, and the passageway IS in the pipe stem, and the chamber or pocket H, a passageway I8 is provided in the offset portion 4 of the body of the pipe and, as clearly shown, this passageway extends transversely with respect to the passage- -way IS in the pipe stem, and one end of the passageway !B is so arranged that it opens ad'- jacent the upperextremity of the air chamber 9.

Thus far, it will be apparent that the chambers and passageways are so arranged with respect to each other that any fine particles of tobacco or ashes will drop through the apertures l2 in the bottom of the bowl 3 and be retained within the air chamber 9, and that the smoke will be directed along a tortuous path, which will cause any impurities inthe smoke, such as. nicotine, to adhere to the walls of the chambers and passageways, and as a result, the impurities are removed; and if so desired the smoke may be filtered prior to its being drawn into the mouth of the smoker. v

An aperture I9 is. preferably provided in the offset portion 4 ofthe body of the pipe in alignment with the passageway I8 so that; after the bowl 3 and the receptacle 8 are removed the passageway 3 may be properly cleaned.

The lower extremity or extension 6 on the offset portion 4 of the pipe bodyis preferably tapered to detachably support the tapered tubular receptacle 8, which serves as a sump for foreign deposits such as a mixture of nicotine and saliva. It will be noted that one sideof the upper ex tremity of the receptacle 8 is cut away as indicated atZU, so as not to project across the passageway l8 and interfere with the circulation of the smoke therethrough. The offset portion 4, adjacent the lower extremity thereof is preferably provided with a rebate 2|, and a recess 22 that receive the receptacle 8, and these insure that the receptacle 8 will be arranged and seated in a predetermined position The rebate provides a shoulder which forms an abutment for the continuation portion or long wall of the receptacle. Obviously, the receptacle may be detachably secured to the offset by a snap action connection.

As clearly shown, the lower extremity or shank of the offset portion 4 is spaced from the side wall of the cup and falls short of extending to the bottom wall of said cup. Said extremity is also provided with a passageway 23 extending therethrough, and in line with thepassageway I5 in the pipe stem. It is through this passageway 23 that any foreign matter, preferably the nicotine and saliva, but in fact any other foreign matter, drops or drains into the sump receptacle 8. It is to be particularly noted that the passageways l6 and 23 in the pipe stem in' the extension 6 are arranged at substantially rightangles to the passageway l8 and aperture l9, and all intersect at the point indicated at 24.

It is thus evident that there is provided a plurality of chambers and passageways, which serve to trap the various impurities in the smoke, and this is of the utmost importance as it is conducive to the health of the smoker. The pipe is sanitary in every respect and odorless to a high degree. It will also be evident that thevarious parts, including the bowl, stem and the receptacle, are detachably connected to the body of the pipe, and this enables the smoker to easily and quickly clean the chambers and passageways, as well as the parts.

Referring to the embodiment of the invention disclosed in Figure 2, it will be apparent that this embodiment is in many respects similar to the construction above described and that there is among other things, two main differences. These differences have to do with the pipe stem, the arrangement of passageways, and one of the chambers.

The body of the pipe, as here shown, is preferably formed or moulded so that the pipe stem 30 is integral with the offset portion of the body of the pipe; thus the body is of a one piece construction to which is attached a removable bowl 3|, and a sump receptacle 32. 33 surrounds the bowl 3|.

The pipe stem is provided with a passageway 34 that extends continuously therethrough and through the offset 35, the latter of'which supports the receptacle 32.

cup 31 with an aperture 38, which register with each other to form a passageway 39 when the receptacle is properly positioned. It is this An air chamber V The receptacle is here shown as being provided with an aperture 36, and the passageway 39, and the air chamber in the rew ceptacle 32 that provide means for connecting and establishing communication between the air chamber 33 surrounding the bowl 3|, and the passageway 34 in the pipe stem. The passageway 39 is preferably arranged transversely to the passageway 34 in the pipe stem, and the junction point between the passageway 39 and the air chamber 33 is preferably located at a point lower than the junction point between the passageway l8 and the air chamber 9 in the construction illustrated in Figure 1. desirable, a pocket 40 may be formed in the offset 35 as to support a suitable filter member 4|.

'Although the receptacle may be frictionally held in place, it is preferably shown in this embodiment as being attached to the ofiset by means of a snap action connection. This connection may be made by providing a detent 42 in the If found receptacle which cooperates with a depression 43 in the offset.

By reason of this arrangement, it will be evi- I formed in a different way than shown inFigures 1 and 2, and this is accomplished 'by providing an annular shoulder portion 53 adjacent the upper and outer extremities of the bowl, in lieu of providing the upper extremities of the cup with an inwardly extending annular portion as shown in the figures mentioned. Although the bowl 52 may be connected to the cup 5| of the pipe in any suitable manner, the connection is here shown as being of the friction type, with the upper extremities of the cup and bowl preferably tapered as indicated at. 54.

In both modifications it will be evident that that portion of the cup which is engaged by the receptacle is more or less semi-cylindrical in form to provide an elongated concave seat for the receptacle in order to more fully insure a good foundation for said receptacle.

In view of the foregoing, it will be evident that new principles of design and construction have been embodied in a pipe whereby to accomplish the objects above referred to, and it is to be understood that various immaterial modifications may be made in the construction without in any way departing from the spirit of the invention.
